UMBRELLA.

SPECIFICATION forming part of Letters Patent N 0. 529,629, dated November :20, 1894.

Application filed January 12, 1894- Serial No. 496.660. (No model.) Patented in England February 14, 1893, No. 3.254; in France March 22. 1893, No. 228,837. and in Germany March 22, 1893,110. 71,265.

To all whom it may concern.-

Be it known that I, WILLIAM Ross, umbrella manufacturer, a subject of the Queen of the United Kingdom of Great Britain and Ireland, and residing at No.45 GeorgeIV. Bridge, Edinburgh, in the county of Mid-Lothian, Scotland, have invented new and useful Improvements in Umbrellas and Parasols, (which have not been patented in any country except Great Britain byLetter's Patent dated the 14th day of February, 1893, No. 3,254 by Letters Patent in France, dated the 22d day of March,'1893, No. 228,837, and by Letters Patent in Germany, dated the 22d day of March 1893, No. 71,265,) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art or manufacture to which it relates to make and use the same.

This invention which relates to improvements in umbrellas and parasols has for its object, first, to dispense with the usual springs fitted into the stick for the purpose of maintaining the umbrella in its open and closed positions and by means of which improvements the weakening of the stick caused by slotting or incising it to receive the springs is obviated, and second, to afiord increased rigidity to the covering when extended.

Figure 1- is a view of an umbrella stick with the improved stretchers and the removable ring for applying a tension thereto. Fig. 2- shows the parts in a different position or partly closed, and Fig. 3- shows the parts closed.

In the drawings the ribs are shown ate, the stretchers at b pivoted to the runner and the elastic removable ring at d. For the purpose of receiving this ring the stretchers are formed with open mouthed hooks at a point inter- 4o mediate of their ends and in their body portions said hooks being formed by enlarging the stretchers at this point and forming the notches or open mouths in these enlarged portions. The elastic springs serve to hold the parts rigidly in open position as in Fig. 1 and serve also to apply a closing pressure thereto when the parts are closed. The runner by this arrangement may be made deeper than usual and when the umbrella is extended the upper end of the runner abuts against the notched ring 9 to which theinner ends of the ribs are attached.

The hooked formation of thestretchers enables the elastic ring to be removed and replaced by any inexperienced person thus affording a convenient means of renewing the tension applying device.

I claim In an umbrella, the stick, the runner, the stretchers and the elastic ring, said stretchers having open mouthed hooks formed in their body portions intermediate of their ends the said ring being seated in said hooked portionsand removable therefrom, and arranged to place a tension on the stretchers tending to hold them open or closed-substantially as described. 4

In testimony whereof I have hereunto set my hand and seal the 20th day of December, 1893.

WILLIAM ROSS. [L. 5.]
